1 Octave is now part of the normal net distribution of Cygwin, available 1 An obsolete version of Octave (2.1.73) is part of the normal net
2 from http://www.cygwin.com. To install the Cygwin package of Octave: 2 distribution of Cygwin, available from http://www.cygwin.com. Check
3 the package list in Cygwin's setup.exe installer if you would like to
4 try using it. However, 2.1.73 is unsupported and we STRONGLY
5 recommended that you use a more recent version of Octave.

4 1. Use your favorite browser to view the page http://www.cygwin.com 7 It should be possible to build Octave on Windows systems with Cygwin,
5 8 but at the time of this writing, there are some performance problems
6 2. Click on the "Install or update now" link. 9 related to the way C++ exception handling is implemented with the
7 10 default Cygwin compiler. This is a known problem with a long history.
8 3. A dialog should appear with the option to run the setup program 11 If you would like to see this problem corrected, please search the
9 from its current location or save it to disk. Either will work, 12 Cygwin mailing lists for threads related to "sjlj exception handling"
10 but I usually choose to save the setup program to disk so that it 13 (or similar).
11 is possible to run it later to update the installation without
12 having to go back to the web page using a browser.
13
14 4. Run the setup program.
15
16 5. Choose "Install from Internet".
17
18 6. Select a root install directory. You may choose any directory, but
19 it needs to have enough space for Octave and all the related
20 tools. Sorry, I don't know how much space that is at present.
21
22 7. Select a local package directory. This is a directory that the
23 setup program will use to temporarily store package files before
24 installing them. It should have plenty of space (probably 70MB
25 or more). You may delete this directory once the installation is
26 complete.
27
28 8. Select your Internet Connection. Probably "Direct Connection" is
29 OK unless you are behind a firewall of some kind that limits your
30 access to the Internet.
31
32 9. Choose a download site. One that is "near" you on the net is
33 probably best.
34
35 10. Select packages. Choose Octave from the Math category and gnuplot
36 from the graphics category.
37
38 11. Once the download and file installation is done, click Finish. I
39 usually choose to create an icon on the desktop and put an icon in
40 the start menu. After you click finish, a series of scripts will
41 run, displaying some output in a terminal window. It will take a
42 few minutes.
43
44 12. To run Octave, start Cygwin. This will bring up a terminal
45 window. In that window type
46
47 startx
48
49 (a running X server is needed for plotting). Running startx will
50 bring up a new window. In that window, type
51
52 octave
53
54 That should present you with an Octave prompt. Type
55
56 sombrero (41)
57
58 at this prompt and a new window with the sombrero plot should appear.
59
60 13. IMPORTANT: to build .oct files (dynamically loaded functions) for
61 Octave, you will also need the octave-headers package. Currently,
62 due to some bugs in the most recent version of the C++ compiler
63 and libraries for Cygwin, you will also need gcc and g++ 3.3
64 rather than 3.4. You can use the setup.exe installer to select
65 and install the older version.
